8 Claims.

Our present invention relates to brush making machines, and moreparticularly to an improved machine for assembling component parts of abrush into a complete unitary structure.

Our present machine is designed to eliminate to as great a degree aspossible the manual assembling of the component parts making up a brush,and particularly a brush of the paint type. In carrying out ourinvention the handles of the brush are stored in a magazine from whichthey may be removed one by one and the brush end of a brush consistingof the tuft of fibers assembled within one end of a ferrule are alsoassembled in a magazine and from which the same may be fed one by one.In accord with our invention the feeding mechanisms for the handles andthe brush units are arranged to operate in synchronism and therefore tosimultaneously remove a handle and a brush unit from the magazines andfeed the same into operative relation to each other in a device which isdesigned to forcibly insert the end of th handle in that end of theferrule which is not occupied by the tuft of fibers constituting thebrush.

A machine embodying our invention contemplates the use of a plurality ofstations at each of which is arranged an operating mechanism forperforming an essential operation on the brush in process of assembly.The stations may be any number that is desired, the number, however,depending on the number of operations to be performed. In a preferredshowing of a machine embodying our invention there are, in addition tothe station for assembling the handle an the brush unit, other stations,as a station for applying nails or other fastening means to one side ofthe brush, a station for printing any desired marking on one side of thebrush, a station for turning the brush over through an angle of 180, aprinting mechanism for performing a printing operation on the other sideof the brush, a station for applying nails or other fastening means tothe other side of th brush, a station at which the brush Or tuft unit iscombed and formed, and a station in which is utilized mechanism forplacing th completed brush in a collecting magazine.

All of the mechanisms at the various stations are operated insynchronism with each other,

for each cycle of operation of the machine.

A feature of our invention is a unitary combined structure forassembling brush elements into a unitary structure and in which a seriesof operations are successively performed on the brush elements.

A further feature of our invention is a unitary combined structure inwhich a plurality of operations are successively performed on brushelements to produce a unitary brush structure and in which suchoperations are successively performed by a series of independentinstrumentalities.

A still further feature of our invention is an improved unitary combinedstructure for performing a series of operations on brush elements toproduce unitary brush structures and in which all of the operations ofthe series are performed simultaneously, each operation being performedon a separate brush assembly.

A still further feature of our invention is an improved unitary combinedstructure in which operations are performed on both sides of a flat oroval brush assembly and in which instrumentalities are provided forrotating the brush assembly through an angle of at some point during theprogress of the brush assembly from one operating instrumentality toanother.

A further feature of our invention is a unitary combined structure inwhich a plurality of working instrumentalities are arranged in seriesrelation, each performing its own operation, and in which the variousinstrumentalities are operated in synchronism with each other and with abrush assembly propelling mechanism for moving the brush assembly beingoperated upon from one working instrumentality of the series to another.

Other features of the invention will appear more clearly as thedescription of the invention progresses.

Referring to the drawings III designates in its entirety the frameworkof a machine composed essentially of end pedestals ii secured in spacedrelation to each other by longitudinal bars is located adjacent thelower end thereof, on the top of which pedestals is mounted a platen ortable II. Secured to the top of the platen or table 13 at one sidethereof and in alignment with each other are pillow blocks l4, and inthese pillow blocks is rotatably mounted a main drive shaft 15. The maindrive shaft I! has attached thereto at one end a pulley l6 and by meansof which the drive shaft 15 is rotated in the desired direction from anysuitable source of power (not shown).

Adjacent the end of the platen or table i3 nearest the pulley IB, and onthe under side of such platen or table are secured a pair of alignedpillow blocks II, (but one of which is shown) and in these alignedpillow blocks is rotatably mounted a shaft 18 and which, as clearlyshown in Fig. 1, is located beneath and extends perpendicular to themain drive shaft [5. Secured to the under face of the platen or table IIand on the under side thereof adjacent to the end remote from the pillowblock I1 is a pair of pillow blocks ll, these pillow blocks being inalignment with each other. Rotatably mounted in these pillow blocks IIis ashaft II which lies parallel to the shaft ll above described.

Secured to the shaft II and spaced apart from each other are twosprocket wheels 2! (but one of which is shown), and these sprocketwheels are respectively in alignment with similar sprocket wheels 22secured to the shaft 20. Over the pairs of sprocket wheels 2| and 22 runendless sprocket chains 23, each of which constitutes a conveyor formoving respectively the handles and the brush ends of the brush to beassembled. Secured to the upper face of the platen or table II aretracks 24 for guiding the upper reaches of the sprocket chains 28 andfor insuring that such upper reach of each sprocket chain runs in astraight line along and above the table II.

Secured to the sprocket chains is, at spaced intervals along the lengththereof, are fingers as and 26 respectively, the fingers II beingattached to one of the sprocket chains ll and the fingers 26 beingattached to the other sprocket chain. The fingers 26 and 26 aredifferent from each other, the fingers 26 being designed to enga e withthe handles-for the brushes to move the same, while the fingers 26 aredesigned to engage with the brush end and move the same. Ob-

viously the sprocket chains II move in unison in the same direction andat the same speed.

Adjacent the end of the platen or table II in proximity to the pillowblocks II, and on the top of such table, is a, bearing standard I. inwhich is rotatabl mounted a shaft II. 5ecured to the shaft II is ahelical pinion II which meshes with and is driven by a helical pinion llsecured to the main drive shaft I6. Secured to or formed integral withthe shaft 2| is a hub 32 provided with a radially extending arm a whichhas formed 'therein a T-slot I4. Mounted for slidable adjustableengagement in the T-slot 34 is the head 35 of a stud l6, threadedadjacent its outer end to receive a nut 31.

On the stud 36 is arranged a bearing washer 38, and between the bearingwasher 38 and the face of the radially extending arm 33 is placed abearing bushing 39. By means of the nut 31, washer 38 and bushing 39 thestud 36 may be securely held in any desired position of the head 35 withrespect to the T-slot 34.

Rotatably mounted on the bushing 39 is one end of a connecting rod 40.The connecting rod 4| has formed at its opposite end a rack 4| whichmeshes with and oscillates a pinion 42 formed integral with a housing44. The rack H is held in engagement with the pinion 42 by a housing 43which encloses the end of the connecting rod :6, and is in turnrotatably mounted on the shaft Formed integral with the pinion 42 androtatable on the shaft 20 is an annular housing 44 in which is housed aclutch member so formed on a hub 46 secured to the shaft 2|. A coverplate 41 may be utilized to close the open end of the housing 44. Theclutch member 46 is provided with a plurality of angular cut-outs "a,the larger length of which forms, with the periphery of the interior ofthe'housing 44, a tapered compartment, as clearly shown in Fig. 15. Ineach of the angular cut-outs 46a is housed a cylindrical clutch memberll.

With the above described construction, and referring to .15, it will beapparent that a movement of the rack ii in the direction of the arrowshown in such figure will result in rotating the housing 44 andconsequently the cylindrical clutch members 48 will move to the highestpart of the angular cut-outs 45a. Under these conditions no rotarymovement will be imparted to the shaft 20. Conversely, when the rack 4|is moved in a direction opposite to that indicated by the arrow in saidfigure, the rotation of the housing 44 will result in the cylindricalclutch members 48 moving toward the narrowest part of the wedge-shapedchamber formed by the angular cut-outs 45a and the periphery of theinterior of the housing 44, to thereby lock the clutch member 45 to thehousing 44 and causing a rotary movement of the shaft in the oppositedirection to the arrow shown in Fig. 15, or in the direction of thearrow shown in connection with shaft 20 in Fig. 14.

Because of the manner of connection of the crank 33 to the shaft 29there is imparted an intermittent rotary movement to the shaft 20, whichthereby results in imparting an intermittent movement of the upper reachof the sprocket chains 23. The extent of such intermittent movement maybe controlled by adjusting the head 35 of the stud 36 in the T-slot 34.The adjustable intermittent movement of the sprocket chains 23 may bethus adjusted to conform with the spacing of the various stations alongthe length of the table I3.

In order to prevent retrograde rotary movement of the shaft 20, andtherefore a retrograde longitudinal movement of the sprocket chains 23we provide the following instrumentalities. One of the pillow blocks I9has formed integral therewith a housing 49 in which is formed an annularchamber. In this chamber is rotatably mounted a clutch member 50,similar in construction to the clutch member 45, but having the cut-outsa therein oppositely arranged. The clutch member is secured to the shaft20 in the usual manner. Fitting in the cut-outs 45a. of the clutchmember 50 are cylindrical clutch members 48. The open end of the clutchhousing 49 is closed by an annular cover plate 5|.

This mechanism is so arranged that as the rack 4| rotates the shaft 20in the direction of the arrow shown in connection with such shaft 20 inFig. 15, the cylindrical clutch members 48 in the housing 50 will bemoved to the large end and thereby prevent retrograde rotary movement ofthe shaft 20.

Mounted on the table I3 between the upper reaches of the endlesssprocket chains 23 is a table or slide over which the handles of thebrushes are moved step-by-step by the endless sprocket chains. Alsomounted on the table I3 and arranged parallel to the table or slide 50is a second table or slide BI over which the brush units of the brushesare moved step-by-step by the endless sprocket chains 23. The tables orslides 60 and 6| extend throughout the whole length of the table I3, andare periodically interrupted wherever such interruption is necessary toprovide a space for some mechanism for performing an operation oroperations on the brush units. The tables or slides 60 and GI are ofappropriate height above the table I3, though not necessarily of thesame height, and such tables or slides at the exit end thereof curvedownwardly as indicated by the reference character 2!, so as to assistin guiding the assembled brushes into a receiving device which transfersthe completed brushes into a collecting mechanism.

Arranged along the length of the platen or table I3 and spaced apartfrom each other, and in such a manner as to be adjustable toward andfrom each other to vary the distance between them, are mechanisms forperforming various operations on the component parts of the brushes.Such operations may be assembling the component parts into a unit brush;securing such component parts in position relative to each other;marking the component parts to designate the type and size of brush orany other information that may be desired; turning the component partsof the brush over through anydesired angle to bring any other desiredportion thereof into operative relation with the assembling mechanism;brushing and treating the flbrous portion of the brush to size thebrush, etc.

The above mechanisms are located on what we call stations, and at eachstation is an operating mechanism, and in the ordinary brush suchmechanisms are as follows. An assembling mechanism for assembling thecomponent parts of the brush into a unitary structure. marking stationwhere the size of the brush being operated on is marked. A first nailingstation where securing means is applied to rigidly hold the componentparts of the brush in assembled relation. A first printing stationwherein desired indicia is printed on one side of the assembled brushes.A turning mechanism for turning the assembled brush unit over to anydesired angle to bring a face thereof into engagement with thesucceeding mechanism, by means of which the printing is applied to theother face of the brush. There is then arranged a second nailing stationwhere additional securing means is applied to the nailing station tohold them to the same in more firmly assembled position. There is thenarranged a brushing station having mechanism for combing, brushing, andcutting, and forming the assemblage of bristles into the desired shapeand form. Other mechanisms may be added if the necessity thereforarises.

The assembling station is designated at the right-hand side of Fig. 1,and the details of such assembling station are illustrated in Figs. 2,3, 4 and 5, and referring to such figures, together with Fig. 1, thereis shown a brush unit magazine 62 having a plurality of superimposedbrush units 63 therein and with the bottommost brush unit 63 resting onthe table or slide BI. There is also arranged a handle magazine 64having a plurality of superimposed handles 65 therein, the bottommosthandle of which rests on the table or slide 60. The brush units 63 andhandles 65 are placed in their respective magazines manually, as usual.

Associated with the magazines 62 and 64 is a mechanism for assemblingthe brush units 63 and handles 65. This mechanism comprises thefollowing instrumentalities. Beneath the table I3 and secured to theunderface thereof, are aligned pillow blocks 66 in which is rotatablymounted a shaft 61. The shaft 61 is arranged parallel to the shaft I8,and, therefore, extends perpendicular to the line of movement of theupper reaches of the endless sprocket chains 23. Secured to'the shaft 61adjacent to the pillow block it beneath the magazine 04 is a cam 00,such cam being provided with a can race On top of the table it andsecured thereto by screws 10 is a slideway ll provided with a v-shapedgroove I2 therein, and which extends longitudinally of the member Ii andparallel to the shaft .1. Secured to the top face of the table II arealigned bearings 13 in which is slidably mounted a shaft 14. Secured tothe shalt l4 and adjustable thereon is a member ll having formedintegral therewith a V-shaped member It which slides in the V-shapedgroove 12 of the member II and is also provided with an upwardlyextending arm'll provided with an enlargement It at the top thereof. Theenlargement II is bored to receive as a sliding fit a shaft ll, suchshaft being secured in adjusted position by the bolt ll. Secured to. orformed integral with one end of the shaft It, is a V- shaped member IIwhich is adapted to engage with the end of a handle ll. Also secured tothe member II and extending downwardly therefrom is a member I! providedat its lower end giving a reciprocating motion to the member Ii.

This motion is of suillcient amplitude to move the end of the brushhandle II from the full line position shown in Fig. 5 to thedot-and-dash line position shown in such figure. This movement issumcient to insure that the other end of the handle I! will be seated inthe ferrule '4 of the brush unit 63.

Secured to the shaft 81 and spaced apart from each other are the cams l5and I. Secured to the table 13 in any desired manner is a member 81which has secured thereto by pin II a shaft 88. One end of such shaft 89protrudes beyond the limits of the member 81 and has rotatably mountedthereon the levers 9i and 92. The levers 9i and 92 are similar inconstruction and constitute mechanism for firmly gripping the ferrule 84of a brush unit 63 against movement during the period when the end ofthe handle 65 is being forced into the ferrule '4 of the brush unit bythe mechanism above described.

The lever 9! is provided on its lower end with a rotatably mounted camroller 83 which engages with the cam surface of the cam 85. The lowerend of the lever 82 has rotatably mounted thereon a cam roller 94 whichengages with the cam surface of the cam 86. The lower ends of the leversII and 82 are constantly urged toward each other by means of a coilspring 95, such spring also tending to keep the cam rollers 93 and 94 inengagement with their respective cams. The upper end of the lever Si isprovided with a V-shaped jaw 96, and similarly the upper end of thelever 92 is provided with a V-shaped Jaw 81. These jaws are adapted toengage with and grip the ferrule 84 of the brush unit 63 and hold thebrush unit relatively stationary during the brush and handle assemblingoperation.

The shaft 61 in its rotating movement has the engagement with theferrule 14 of the brush unit 08, and into position where the fingers 2|It on the endless conveyor chains 28 and referring to such figures,there is shown an arm or pedestal ill secured to the top of the table IIby bolts ill, said arm being provided with a curved magazine ormagazines I for holding and positioning in proper order the plurality ofstaples I04. In alignment with the arm or pedestal ill and secured tothe top of the table II is a pedestal I" provided at the end adjacentthe delivery end of the magazine or magazines I with a Jaw opening I"and through which the ferrule I4 of the brush unit 83 may be fedtransversely of the pedestal ill.

Located within the jaw opening I" is the table or slide Ii. Also, on thelower portion of the jaw opening i", and beneath the delivery end of themagazine or magazines III, is an anvil I". In the upper end of the jawopening III is provided a vertical slide Ill in which is slidablymounted a crow head in carrying the staple propelling member or membersIll, and which engage with the staples H14 in the magazine or magazinesI II, and drive the same into and through the ferrule 04 of the brushunits 63, and into the handle I, thereby firmly attaching-the handle IIto the brush unit II. On the upper end of the pedestal III! is a shaftill on which is pivotally mounted a lever H2 one end of which isprovided with a cam roller H3, adapted to be engaged by the workingsurface of a cam 4.

This cam H4 is provided with a rather rapid rise lit for rapidly movingthe end of the lever ill containing the roller H3 upwardly. A coilspring lilo, attached one end to the lever H2 and the other end to thepedestal I". maintains the cam roller lit in engagement with the cam H4.The other end of the lever H2 is pivotally attached to one end of aconnecting link ill. The other end of the connecting link H8 ispivotally attached to the top 01 the cross head I". The cam IN issecured to the main drive shaft i5, preferably by means of the threadedbolt ll'l. By means of this connection the cam 4 may be readilydisconnected from driving connection with the main drive shaft IS. Theform of connection is such that any other form of tion, above described,to the first nailing station described above and illustrated in detailin Figs. 6, '7 and 8, thereby bringing the assembled brush units intooperative relation with respect to the mechanism above described.

The nailing operation takes place in the manner just described, and whenthe staple engaging members IIO have cleared the ferrule 84 of the brushunit 63, the cam roller II3 will be in engagement with the cylindricalportion of the cam II 4. The next intermittent step of movement of theendless conveyor chains 23 will,

therefore, move the assembled brush unit from the first nailingposition, above described, to the ment for heating the stamp or die anda movable stamp or die holding structure I22, which structure is movedperiodically downward to bring the stamp or die into engagement with thebrush handle being operated upon. Preferably, the printing mechanismoperates in the well known manner where heat and pressure are applied toa stamp or die, and the heat and pressure are utilized to transfer someof the color from the roll I2I carrying colored material to the handle65 of the .brush being operated on.

Preferably, there are twoof the printing stations and, therefore, two ofthe printing mechanism, it being desired to print indicia on two sidesor faces of the brush handle I55. Under these circumstances, therefore,it is desirable and practically necessary to interpose between theprinting mechanism a mechanism for tuming the brush assembly over, so asto bring the unprinted surface thereof into engagement to be operated onby the second printing mechanism. In Fig. 1, the second printing stationis designated by the reference numeral I23, and interposed between thestations I20 and I23 is the turning station designated by the numeral I24.

Assuming, therefore, that the first printing operation has beenperformed and that the endless sprocket chains 23, in their intermittentmovement, have moved the brush assembly, just printed, to the nextsucceeding operating mechanism-in this instance a turning mechanismtheturning mechanism will take the brush assembly from the tables or slides50 and GI and will rotate the same through an angle of 180, after whichthe turning mechanism will deposit the brush assembly on the tables orslides 80 and SI and be in position to operate on the next succeedingbrush assembly.

The turning mechanism is illustrated in detail in Figs. 9, 10, 11 and12, and referring to such figures there is shown'at the turning stationI24, and below the table I3, the aligned bearings I25 and I26 andinthese aligned bearings is rotatably mounted a shaft I21. Secured tothe shaft I21 is a gear I28which meshes with and is driven by a gear I29mounted on. and forming part of the first printing-mechanism. Secured tothe shaft I21, adjacent the gear I28, is a cam I30.

Mounted on the top of the table I3 is a pillow block I3I in which isrotatably mounted a shaft I32. Secured to the shaft I32 and extendingdownwardly therefrom is a lever I33 provided at its lower end with acamroller I34 engaging the surface of the cam I30.- Also secured to the.shaft I32 is an arm I35'provided at its outer end witha table orplatform I36 adapted to be brought up through an opening in the table orslide 60 and support the handle 65 of a brush assembly, as clearly shownin Fig. 11.

Secured to the shaft I21 at the end remote from the gear I28 is a gear I40. As may be seen from the end elevation in Fig. 10, this gear I40 is asegmental gear one half of the periphery of the gear being provided withgear teeth I while the remaining half of the gear I42 is plain ortoothless. The gear I40 is adapted to mesh with and drive a gear I43which is secured to a shaft I 44 rotatably mounted in a bearing I45secured to the upper surface of the table I3. By reference to Figs. 10and 11, it will be seen that the gear I43 is divided, about itsperiphery into four zones, such zones being arranged in pairs anddiametrically arranged. For example, diametrically arranged on the gearI43 are the arcuate toothless portion I42 on the gear I40 to therebypermit the gear I40 to rotate to a certain angular space while gear I43remains stationary. Also, diametrically arranged on the gear I43 are theteeth- I41, which teeth are adapted to be engaged by the teeth I4I onthe gear I40, and whereby the gear I43 may be rotated to bring thearcuate portions I46 successively into operative relation with thetoothless portion I42 of the gear I 40. As the gear I40 is continuouslyrotating it will be apparent that the gear I43 will be intermittentlyrotated and will make one revolution to two revolutions of the gear I40.

Secured to the shaft I44 at the end remote from the gear I43 is acylindrical disk-like member I48, provided with aligned bosses I49dimetrically arranged on one face of the same. Rotatably mounted on eachof the bosses is a shaft, as the shaft I50. Secured to one end of eachof the shafts I 50 on one side of the disk I48 is a jaw member I5I.Secured to each of the shafts I50 on the other side of the disk-likemember I48 is a lever, one of such levers being designated by thereference numeral I52, and the other lever being designated by thereference numeral I53. To one end of the lever I52 is attached, throughpin I54, a coil spring I55, the other end of this coil being attached,through pin I56, to the disk-like member I48. The coil spring I55,therefore, as viewed in Fig. 10, tends to rotate the lever I52 in aclockwise direction about the shaft I44. The other end of the lever I52has rotatably mounted thereon a cam roller I51. Also, this other end ofthe lever I25 has pivotally attached thereto one end of a connecting rodI58, the other end of this connecting rod being pivotally attached toone end of the pivoted lever I53. The end of the lever I53 remote fromthe connection thereto of the link I58 has rotatably mounted thereon acam roller I58, similar in construction to the cam roller I51.

As the shaft I21 rotates, the gear I40 is likewise rotated, that iscontinuously and, therefore, the gear I43 will be intermittentlyrotated, with a slight pause between each intermittent rotary movement,this action being possible because of the arcuate portions I46 of thegear I 43 and the toothless portion I42 on the gear I40, as abovedescribed. I 1

The jaws II carried'by the shafts I88 will, therefore, be likewiserotated and assuming the position of the parts being that shown in Figs.and 11, it will be apparent that when the shaft I21 rotates so as tobring the teeth I of the gear I40 into mesh with the teeth I41 on one ofthe sectors of the gear I48, that such gear I48 will be rotated throughan angle of 180 so as to bring the now lowermost arcuate portion I48 ofthe gear I40 into the uppermost position and, therefore, vice versa,thereby, to rotate the Jaws I5I and any article that may be carriedthereby through an angle of 180.

As the articles being worked on by the present machine are at thepresent time brushes, particularly brushes of the paint type, and assuch brushes are normally flat on two opposite faces and it is desiredto perform certain operation on such opposite faces, the jaws III are soarranged as to hold such paint brushes. to always present the fiat facesof the brushes to the working instrumentalities. This rotary movement iscontrolled by the gears I40 and I48, but has no effect on either openingor closing the jaws I" to permit the insertion and gripping, for theholding of the brushes therein.

This latter is accomplished in the following manner. On the shaft I21 issecured a gear I58. On the shaft I44 is'secured a gear I80 which issimilar in pitch and diameter to the gear I 88. Interposed between thetwo gears I 58 and I88 and rotatably mounted on a stub shaft I8I is anidler pinion I82. In a bearing block I88, secured to the top of thetable I8, is a shaft I84 to which is secured a gear I85. To thehub ofthe gear I85 is secured a cam I88. As the shaft I28 is continuouslyrotating the shaft I84 will likewise be continuously rotating, and,therefore, the cam I 88 will always be in motion, although not always inaction. The train of gears I58,- I80, I82 and I85 is so proportionedwith respect to the gears I48 and I43 that the cam I88 will be broughtin engagement with one or the other of the cam III separated from eachother or in open position, when the cam I88 rides past the cam rollerI81 or I884, as the case may be, the coil spring I88 rotates the leversI82 and I88 and brings the jaws I5I into their gripping or closedposition onto the next succeeding brush assembly.

From the turning mechanism above described the assembled brush isbrought into operative position with respect to' the second printingmechanism, designated in Fig. 1 by the reference numeral I28, Thissecond printing mechanism is identieal'in construction and operation tothe first printing mechanism, I28 heretofore described, and, therefore,will not be described in detail.

In the continued intermittent movement of the endless conveyor chains23, the completed brush assembly, after having been operated upon by thesecond printing mechanism I28 is moved into operative association with asecond nailing mechanism I10. The particular details of the nailingmechanism are identical with the nailing mechanism heretofore describedand illustrated in Figs.

= 6, '1 and 8, and. therefore, a further description rollers I51 andI58a. In other words, assuming the parts of the device to be in theposition shown in Figs. 10 andll it will be noted that the gear teeth Iare about to intermesh with the gear teeth 1 on one segment of the gearI48 and to rotate such gear I43. In this position the jaws ii are nowclamped on the ferrule 84 of a brush unit and hold the brush firmlyagainst movement. The gear I85 is rotating, but the cam rollers I51 andI58a will not be engaged by the cam I85 at this time. The gear 0rotating, will rotate the gear I43 so as to bring the now uppermostarcuate surface I48 into the lowermost position as the beginning of thetoothless portion I42 of the gear I40 comes into play and the gear I48stops with the lever I53 occupying the position now occupied by thelever I52 and bringing the cam roller I58a thereon into the position nowoccupied by the cam roller I5'I in Fig. 10. When this thereof is notdeemed to be necessary.

After leaving the second nailing mechanism I10 the brush assembly isbrought into association with a brushing and forming mechanismdesignated in Fig. 1 generally by the reference numeral "I, andillustrated in detail in Fig. 13. Referring to such Fig. 13 it will benoted that the slideways 88 and H are associated therewith and overwhich slides are moved by the endless conveyor chains 28, the completedbrush assembly including the handles 85 and brush element 88.

On top of the platen or table I3 is mounted a base I12 provided at itstop with a bearing I13 which is rotatably mounted a shaft I 14. Securedto the shaft I14 is a pulley I15 which is in alignment with a pulley I18secured to the main drive shaft I5. Over the pulleys I15 and I18 runsthe endless belt I11 and by means of which power is transmitted from theshaft I5 to rotate the shaft I14.

Pivotally mounted on the shaft I14 is a hub I18 provided with adownwardly extending arm I18 having a bearing I at its lower end.Rotatably mounted in the bearing I80 is a shaft I8I. Secured to one endof the shaft I8I is a pulley I 82 which is in alignment with a pulleyI83 secured to the shaft I14, and over the pulleys I82 and I83 runs anendless belt I84, and by means of which power is delivered from theshaft I14 to rotate the shaft I8I. Secured to the shaft I8I, on theopposite side of the bearing I 80, from the pulley I82, is a circularbrush I85 which rotates in the direction of the arrow shown in Fig. 13.Also secured to the hub I18 is a downwardly extending arm I88, on theouter end of which is rotatably mounted a cam roller I81. Secured to themain drive shaft I5 adjacent the pulley I18, and in position to beengaged by the cam roller I81 is a cam I88. The function of the cam I88and cam roller I 81 is to give to the circular brush I 82 an oscillatingmovement about the shaft I14 as a center, to swing the circular brushI82 into and out of operative position with respect to the bristles ofthe brush element 88, as clearly shown in Fig. 13.

In order to provide that the brush assembly composed of the handle 85and brush unit 88 is held in fixed operative relation to the brush I82we have provided the following instrumentalities. Adjacent the endlessconveyor chain 23 carrying the fingers 25 on top of the platen or tableII is secured a pedestal I88. Mounted in such pedestal I89 is a shaft I90. Secured to the shaft I90 is a lever, one arm I9I of which is curvedand provided at its outer extremity with a clamping jaw I92 which firmlyclamps the handle 65 of the assembled brush onto the slide 60.Intermediate the ends of the lever arm I9I is provided a stop I93 whichnot only engages the end of the handle 65 to prevent rearward movementthereof, but which positions the brush unit 66 in operative relation tothe circular brush I82. The other arm 194 of the lever, secured to theshaft I90, has pivotally attached at its free end, one end of a shaft orr'odI95. Secured to the other end ofthe shaft or rod I95 is a forkedmember I96. The spaced arms I91 of which straddle the main drive shaft Iso as to permit rotary movement of the main shaft I5, while yetpermitting a sliding longitudinal movement of the forked member I96 onsuch shaft. On the forked member I96 is mounted a stub shaft I98, onwhich is rotatably mounted a cam roller I99 and this cam roller I99engages with the cam face of a cam 200, secured to the main drive shaftI5.

The cams I88 and 200 are so formed and so disposed on the main driveshaft I5, and are so related to each other and to the mechanismsoperated or controlled thereby, that as the brush assembly formed of thehandle 65 and the brush unit 66 are moved into proper position by thefingers 25 and 26, carried by the endless conveyor chains 23, the leverarm I9| is operated to bring the clamping jaw I92 and stop I93 intooperative relation to the handle 65, to .thereby move the handle to theright as shown in Fig. 3 a sufficient distance to bring the brush unit66 into operative relation to the circular brush I82 and to clamp thebrush assembly in fixed position on the slide 60. After this clampingand positioning operation has taken place, the cam I88, engaging withthe cam roller 881 on the arm, rotates the arm I19 about the shaft I14as a center, and brings the circular brush I85 into operative positionwith respect to the bristles of the brush unit 66 to thereby brush andcondition the same, after which the brush I85 is swung out of the wayand into the position now shown in Fig. 13. Immediately thereafter thecam 200 operating in conjunction with cam roller I99. moves the rod orshaft I95 to the right, as shown in Fig. 13, raising the lever arm I91to thereby free the assembled and cleaned brush and permit the same tobe moved onward.

Upon leaving the brushing unit I1I described above, the assembled brushmoves along the slides 60 and BI and downward along the curved portion20I thereof. From the bottom of the curved portion 20I of the slides 60and BI, the assembled brushes are collected in a holder or magazine 202,and the transition of such assembled brushes from the curved portion 20Ito the magazine 202 is accomplished in the following manner. I

Referring back to the second printing mechanism I23, it is noted thatthis printing mechanism is provided with a main shaft 203. On such shaftis secured a face plate 204 provided with aradially extended crank pin205,- Pivotally attached to the crank pin 205 is one end of a connectingrod 206. The other end of the connecting rod 206 is piovtally attachedto the lower end of a lever 201 which is pivotally mounted intermediateits ends, on a shaft 208 carried by a bearing member 209, secured to theunder face 'of the platen or table I3. The end of the lever 201, remotefrom the pivotal connection of the cess 2I0 into which the brushassembly slides from the curved portion 2M 01' the slides 60 and 6|. Therotation of the main drive shaft 208 of the second printing mechanismI23 by the mechanism above described imparts an oscillating movement tothe lever 201, the end of such lever, within which is.provided therecess 2l0, swinging from the full line position shown in Fig. 1', inwhich it receives the'assembled brush, to the dot-and-dash line positionshown in Fig. 1, where the finished brush is forced into the collectingmagazine 202.

Referring now to Fig. 16, there is shown a plurality of viewsrepresenting the complete series of operations above described andwherein the handle 65 and the brush assembly comprising the ferrule 84and bristles 66 are shown in disassembled and assembled position,representing the condition of these elements when the same are in theassembling unit heretofore described with respect to Figs. 2, 3, 4 and5. After the assembling operation, the brush elements 65, 66 and 84 areas shown in the group designated Assembling. After the first nailingoperation by the mechanism designated generally in Fig. 1

by the reference numeral I00, and illustrated in detail in Figs. 6, 7and 8, the appearance is that shown at the point designated "Firstnailing. The first printing operation is sufiiciently illustrated by theappropriate character in Fig. 16, and also the turning operation isdesignated as being a turning operation by the arrow in the appropriatefigure, whereas the second printing and second nailing operations arealso sufiiciently indicated in the appropriate stations. In the cleaningoperation, so designated, the circular brush I82 has been shown inconnection therewith in order not to confuse the brushing operation withother operations which have taken place.

In Figs. 17, 18 and 19, a different form of brush from that illustratedin Fig. 16 is shown, and in which the ferrule 84 of Fig. 16 hassubstituted therefor a ferrule 2II formed of any suitable,

but preferably of non-metallic material. Further, and as shown in Fig.18, the end of the handle 65 is shown with a wedge shaped split 2I2therein and in which is positioned a wedge 2I3, preferably of wood, andat any rate of nonmetallic material. During the assembling operation,therefore, and with regard to the type of brush illustrated in Figs. 17,18, and 19, the assembling of the brush units 65 and 66 results in theforcing of the wedge 2I3 in the wedge shaped cut in the end of thehandle 65. The ferrule 2| I, in this form of brush, has the perforationtherethrough undercut as indicated by the reference numeral 2I4, withthe result that the material of the end of the handle 65 is forcedoutwardly at its ends as shown in Fig. 19 as the wedge 2I4 is driveninto the handle 35. In this type of brush, no fastening or nailingoperations take place, and it is possible to either remove the nailinginstrumentalities illustrated in Fig. l, and rearrange all the otherinstrumentalities, or merely disconnect the nailing instrumentalitiesshown in Fig. 1 from the operating power so that while the brush unitswill stop at the nailing stations no nailing will take place.

Whereas this invention has been described pursuant to specific formsthereof, it will be understood and agreed that many changes andmodifications may be made without departing from the spirit of theinvention.
